Clara Oswald still felt a thrill of excitement every time she led Jack Harkness to her bedroom aboard the TARDIS.

Jack looked at Clara with a mixture of amusement and curiosity as she closed the door behind them and dangled handcuffs in front of him teasingly. "Me or you?" He grinned.

Clara smiled as she climbed onto the bed and straddled Jack's hips. "You," she whispered, running her fingers through his hair.

Jack chuckled. "I can't wait," he said, his eyes sparkling with mischief.

Clara leaned down and pressed her lips to Jack's, kissing him deeply. She could feel his cock hardening beneath her, and she ground her hips against him, feeling the heat of his desire. The cuffs clicked around his wrists, cuffing him to the bed.

She broke the kiss and sat up, looking down at Jack with a wicked grin. "I'm going to spank you now, Jack," she said, her voice low and sultry.

Jack raised an eyebrow. "Oh really?" he said, his voice dripping with sarcasm. "And why would you want to do that?"

Clara leaned down and whispered in his ear, "Because I want to see you squirm, Jack. I want to see you beg for more."

Jack's eyes widened as Clara's words sank in. He knew she was serious, and he couldn't help but feel a thrill of excitement at the thought of being at her mercy.

Clara raised her hand and brought it down on Jack's ass-cheek with a loud smack. Jack yelped in surprise, and Clara laughed. She spanked him again and again, each slap sending a jolt of pleasure-pain through his body.

Clara leaned down and kissed Jack again, her lips soft and gentle against his. She could feel his cock throbbing against her, and she knew he was enjoying this as much as she was.

She broke the kiss and sat up, reaching for the tickler she had hidden under the pillow. She ran the feathers over Jack's chest and stomach, watching as his muscles tensed and relaxed under her touch.

Jack laughed, trying to wriggle out of her grasp. "Stop it, Clara!" he cried, his voice breathless.

Clara grinned and continued to tickle him, her fingers dancing over his skin in harmony. She could feel his cock twitching against her, and she knew he was close to cumming.

She leaned down and took him in her mouth, her lips wrapping around his shaft as she sucked him deep. Jack groaned, his hips bucking as he thrust into her mouth. Clara sucked him harder, her tongue swirling around his cock as she brought him to the brink of orgasm.

She continued to expertly tease him with the tickler as she sucked him off, the light feathers brushing unbearably against the tops of his thighs and his balls. It was a pleasure barrage he couldn't withstand for long.

Jack cried out as he came, his cum filling Clara's mouth. She swallowed it down, savoring the taste of him. The little brunette looked up at him with a grin.

Clara unlocked Jack's handcuffs, freeing him from her bed. She lay back, her body slick with sweat as she watched him get up.

Jack turned to her, a wicked grin on his face. "My turn," he said, his voice low and dangerous.

Clara felt a thrill of excitement as Jack clicked the handcuffs in place on her slender wrists, binding them to the bedpost.

Jack spanked Clara harder than she had spanked him, each slap sending a jolt of pain through her body. She cried out, her body writhing under his touch. Her ass reddened with each blow.

Jack leaned down and whispered in her ear, "You like that, don't you, Clara?"

Clara nodded, her breath coming in ragged gasps. She could feel her pussy growing wet, her body responding to Jack's rough treatment. "Mhm-hm" she moaned in a positive. He grinned, spanking her again to make her cry out.

Jack reached between her legs and began to finger her, his fingers sliding in and out of her wet pussy. Clara moaned, her hips bucking as she ground herself against his hand.

Jack pulled his fingers out of her pussy and slid them into her asshole, fucking her with his fingers as she moaned and begged for more. "Oh god," she cried out as he pumped his fingers in and out of her tight asshole. Her eyes watered from the sensation.

Jack turned her over suddenly, pushing her onto all fours as he positioned himself behind her. He slid his cock into her pussy, fucking her hard and fast as she cried out in pleasure.

Jack positioned himself behind Clara, grabbing her hips firmly. He thrust into her hard and fast, causing Clara to cry out in pleasure. Jack spanked Clara's ass as he fucked her, leaving a red handprint on her pale skin. Clara moaned louder with each slap, her pussy clenching around Jack's dick.

Jack reached around and started rubbing Clara's clit as he fucked her harder and faster. Clara's moans turned into screams of pleasure as she came hard on Jack's dick. Jack didn't stop fucking her, he just kept going harder and faster.

Jack pulled out of Clara and flipped her over onto her back. He spread her legs wide and started eating her out, licking and sucking on her clit. Clara moaned and thrashed on the bed, her orgasm building up again.

Jack slid two fingers into Clara's pussy, fucking her with them as he continued to eat her out. Clara's moans turned into screams as she came again, her pussy contracting around Jack's fingers.

Jack crawled back up Clara's body, his dick hard and ready to go again. He slid into her easily, her pussy still slick with cum. Jack started fucking Clara slowly, savoring every inch of her tight pussy.

Clara wrapped her legs around Jack's waist, pulling him deeper into her. She moaned as Jack fucked her, her pussy clenching around his dick. Jack leaned down and kissed Clara, their tongues dancing together as they fucked.

Jack reached down and started rubbing Clara's clit again, making her moan louder. Clara's pussy clenched around Jack's dick as she came again, her orgasm ripping through her body.

Jack kept fucking Clara, his dick throbbing as he felt his own orgasm building up. Clara looked up at Jack, her eyes filled with lust. She begged him to cum inside her, to fill her pussy up with his seed.

Jack groaned as he came, his dick throbbing as he filled Clara's pussy up with cum. Clara moaned as she felt Jack cum inside her, her pussy contracting around his dick. Jack collapsed on top of Clara, both of them panting and sweating.

Jack looked down at Clara, a satisfied smile on his face. Clara smiled back, her body still trembling from her orgasms. Jack leaned down and kissed Clara, their tongues dancing together as they lay in bed, covered in sweat and cum.

As they caught their breath, Jack let his fingers gently rub and stroke Clara's shoulders and thighs and sides. Finally he uncuffed her. Clara rubbed her wrists then flicked her brown hair out of her eyes.

Clara looked up at Jack, a wicked grin on her face. "My turn again," she said. The handcuffs were back on Jack before he could reply. His eyes widened as this time Clara produced a nine-tailed whip. "You were good at that," she teased, trailing the whip down his chest slowly, "but I promise you, Captain…"

Crack.

"I'm better."
